Hi,

When I stop adding torque to my wheels car stops then it start moving again due to terrain elevation - and it is right. But how do I fully stop the car like a handbreak effect?

Thanks,
Dirso.

Ogre::Real MaxBrake = tire->calculateMaxBrakeAcceleration();



tire->setBrakeAcceleration( MaxBrake, MaxBrake );

this is an emergency brake, that will stop the tires instantly.
for normal brakes, you would have a fixed value (the max strength of the brakes) that you pass as the second parameter to setBrakeAcceleration().

Should I call this function every frame I want the car not to move?

Thank you very much!!! Will the car slide if it be in too high speed, like a normal car would?

It didn't work

The car still moves if I don't use any torque and the terrain is not totally plane.

The car doesn't slide either. Is there any kind of contact I should define to make the car slide?

It's much better now. I still had a small, really small acceleration. Is there a way to freeze the car?
